Typically how long will it take swelling from arm lift to subside completely?

Typically it will take at least three months for the majority of your swelling to go away. That said, it can take up to a year to see your final results. Stay patient and stay in touch with your surgeon. It is imperative
that you seek the advice of a plastic surgeon who is certified by the American
Board of Plastic Surgery and has extensive experience in brachioplasty / arm
lift.

I wish you the best.

For swelling to go away completely, it typically takes approximately three months.        ///////

Most swelling ought to resolve in 6 weeks or so, but it is likely that at least some edema may persist longer, up to about 3 months after this procedure, if properly performed.  In a few cases, prolonged edema is possible.
